It is known for its excellent properties such as durability, water resistance, and high adhesion to various surfaces. In this page, we will discuss in detail the various aspects of cutback bitumen RC-250, including its production, specifications, advantages, applications, and safety tips.

What is Cutback Bitumen RC-250?

Cutback bitumen RC-250 is a type of bitumen that is prepared by mixing bitumen with a petroleum-based solvent. The “RC” in its name stands for “Rapid Curing,” which means that it dries and sets quickly, allowing for faster construction times.

Cutback bitumen RC250 is highly preferred in road construction, pavement, and maintenance as it offers a durable and cost-effective solution. Its unique formulation provides excellent resistance to water, weathering, and aging, making it ideal for use in areas with extreme weather conditions.

Cutback bitumen RC-250 History and Other Names

Cutback bitumen RC-250 has been used in the construction industry for several decades. Its history dates back to the early 20th century when it was first used as a road surfacing material. Over the years, it has gained popularity due to its excellent properties and versatility.

Cutback bitumen RC-250 is also known by several other names, including:

Rapid Curing Cutback Bitumen

  • Cutback Asphalt
  • Liquid Bitumen
  • Bitumen Emulsion
  • Bitumen Paint

Cutback bitumen RC-250 Production

Cutback bitumen RC-250 is produced by mixing bitumen with a petroleum-based solvent such as kerosene or diesel. The ratio of bitumen to solvent varies depending on the desired consistency and viscosity of the final product.

The production process involves heating the bitumen to a high temperature to make it more fluid and easier to mix with the solvent. The solvent is then slowly added to the bitumen while stirring until the desired consistency is achieved.
